Hi Lynne I play Recorder and Bombarde amongst other things.
I use Pakistani Bagpipe reeds for the bombardes I play (about 50p each from a company called FCN) and they work well. I use a more Arabic technique that does not touch the reed blades but they work in the traditional manner too. The important thing is the staple diameter if it's too large the second octave will be sharp and visa versa. The Asian made Pipe reeds are very variable so you might have to order a few a few times but at the price it's well worth it in the end.
